«لَا بَصَلْتَكْ وَلَا عِينِي تِدْمَعْ»

The onion stands for a modest favor or gift, and the streaming eyes for the distress that comes along with it. The speaker says they would rather lose the small benefit than suffer the sting that always arrives with it.

More broadly, the line rejects a specific favor that is followed by something painful, of whatever kind. A benefit offered on those terms is not worth having, so the speaker gladly lets both the gift and its hurt go.

Said by someone refusing help or a gift from a person whose generosity tends to bring hurt or distress afterward. It rejects that particular favor, not kindness in general, signaling that going without is preferable to accepting a benefit with such a cost.
